Well, those websites aren't that informative about the inherited diseases they are able to locate in any give DNA test. Still, it's something to consider. I imagine anyone really interested could email them for further details of what they can potentially spot in say a Yorkshire Terrier in the way of hereditary medical conditions. I forgot whether you posted it or not, but did your Bella's test include any information on her tendency to develop LP or anything like that?
BTW, I hope Bella is doing well after her surgery and have meant to visit your thread to ask how her weight-bearing and stiffness in the joint are going?
